Solution
Crystals are the purest solid forms of a substance, having a natural geometric shape.
To prepare the crystals of sodium chloride, a solution containing maximum amount of common salt is dissolved in boiling water, which is then filtered to remove the insoluble impurities. This filtered solution is allowed to sit for few hours, without disturbing it. The sodium chloride accumulate to form crystals with definite geometric shapes, leaving behind the impurities in the solution.
